because it is devices
Output - because it is outputting power to the rest of the device
UPS is Uninterruptable Power Supply. It is neither input not output. It supplies electrical power to a computer when the main electrical supply is interrupted. It does not handle data in any way.
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. PSU is a output device because it is outputting power to the rest of the device. Most personal computers can be plugged into standard electrical outlets.
Yes. (For any pairing of power supply and device, as long as the voltages are a match (in your case: 9v), and the output (in amps or milliamps (A or mA) of the power supply IS EQUAL TO OR GREATER THAN the current required by the device (in your case 1300mA or higher) then you will be fine. Yes it is suitable: The OUTPUT VOLTAGE (5v, 9v, 12v, etc) of a power supply MUST BE EQUIVALENT to the required voltage of the device to which it is to be connected, whereas the output CURRENT (500mA, 1A, 1500mA, 2A... etc) offered by the power supply MUST BE AT LEAST EQUAL TO OR GREATER THAN the current required by the device to which it is to be connected. (in your case, for example, as long as the power supply is rated at 9v, you could use one that has a rating of 1300mA, 1400mA, 1500mA, 1A...and so-on, without any damage to either device)
No you can not. The power supply output of 5 volts is under sized. There is no way that a 45 volt device would operate from it. You will need to find a power supply of 45 volts.
No you can not. The power supply output of 1.2 amps is under sized. You would need to have a power supply of 3 amps or larger.
Line refers to the a.c. supply line. Line regulation is the change in output of a device, usually a power supply, which is due to variations in the voltage of the a.c. supply.
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.

Yes, you can use a 1A power pack for a 500mA device. The power pack will supply the necessary 500mA the device requires, with some extra capacity. Ensure that the voltage output matches the device's requirement to avoid any potential damage.
The terminology would typically reference a device such as a power supply, charger, diverter or transformer. The Input Voltage is the voltage supplied to the device to make it work. The Output Voltage is what the device supplies to an application. For example, a power supply for a laptop might convert 120 VAC to a voltage like 19.5 volts (A Sony Laptop) for charging a laptop battery.
Laptop power supply provides a much lower watt output compared to desktop because its powering a smaller and more energy efficient device. Do not try mixing them
